Dead Calm(1989) [Orpheus Cruise Girl]: Killed (off-screen), along with everybody else on the boat, by Billy Zane; she only appears on a videotape from before the murders when Sam Neill investigates the boat. (There are also numerous body parts shown in the boat, but they're obviously special-effects dummies and prosthetics.)

Web of Deception(1994) [Corrie Calvin]: Commits suicide by shooting herself in the chest, rigging up the gun in such a way as to frame Powers Boothe for her "murder." (Thanks to Indrico)
